Two things:
 - check that your disk devices are actually readable (and probably
   writable, I botched that, cf. David's mail) by group disk
 - your being added to disk is effective *after* logging in after
   you'd made the change; if you want to bypass it, there is the
   command 'newgrp'; you can check which groups you are "in" by
   issuing the command 'groups': 'disk' should be in there.

How does "no effect" look like?
